Chapter 6.1, Problem 2cT

We may think of a bulb as percentage an obstacle, or resistance, to the current in the circuit.
1. Thinking of the bulb in this way, would adding more bulbs in series cause the total obstacle to the flow, or total resistance, to increase, decrease, or stay the same as before?

2. Formulate a rule for predicting how the current through the battery would change (i.e., whether it would increase, decrease, or remain the same) if the number of bulbs connected in series were increased or decreased.

Describe how the current flowing through the resistor varied as the voltage was increased? Based on the graph, What do the slopes of the best fit lines represent? Explain  Do you consider the resistor as ohmic? Why or why not?
1. What is the equivalent resistance if you connect three 10.0 Ω resistors in series? 2. What is the equivalent resistance if you connect three 10.0 Ω resistors in parallel?  3. Calculate the current in each 10.0 Ω resistor in the series circuit and in the parallel circuit if the power supply is 60.0 V.
Given the circuit below: If all the currents flowing through R1, R2, and R3 (I1, I2, and I3, respectively) are going in the top junction, what is the equation resulting from applying the Kirchhoff's loop rule for a clockwise loop around the perimeter of the circuit?
